My stepson (aged 12) has a project coming up and he has decided to do it on Einsteins theory of relativity. Rather than telling him not to be so silly and do something less complex, I figured we might ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

It might not be obvious to those of us only grappling with more mundane concerns, but for cosmologists bent on unlocking the universe’s deepest secrets, there’s no shortage of problems keeping them up ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...
